SPECIFICATION forming art of Letters Patent No. 631,825, dated August29, 1899.

' A plic i e May 4, 1899. Serial No. 715,532. (No model.)

To aZZ whom it may concern.-

Be it known that I, HORACE SEE, of the city, county, and State of NewYork, have invented a new and useful Improvement in Ash- Ejectors, ofwhich the following is a specification.

My invention relates to that class of ashejectors employed on vessels inwhich the ashes are forced overboard through a discharge-pipe by meansof a water-jet.

My invention consists in the construction of the apparatus whereby thevalves controlling the discharge and also the actuating-jet may beoperated simultaneously, also whereby the feed-door cannot be secured inopen position until said valves are opened, also whereby the said valvescannot be closed while said feed-door remains in open position, alsowhereby the ashes are prevented from choking the delivery opening andthe larger masses therein broken up, and also whereby the outcomingstream of ashes and water is directed toward the stern of the vessel,'to gether with the various combinations of parts, all as hereinaftermore particularly pointed out in the claims. 1

In the accompanying drawings, Figure 1 is a side elevation of myimproved ash-ejector, showing the upper discharging-pipe in verticalsection. Fig. 2 is a front view showing a portion of the hopper-doorbroken away. Fig. 3 is a top view with the upper portion of the hopperbroken away to show the arrangement of the projections in the openingleading from the hopper to the discharge-pipe.

'Similar numbers of reference indicate like parts.

1 represents the side of the vessel in section, in which my device isinstalled.

2 is a fore-and-aft bulkhead, in an opening in which the hopper isplaced,so that said apparatus lies mainly between said bulkhead and theside of the vessel.

3 is a hopper provided with a flange 4, which rests against the inboardside of the bulkhead.

5 is a discharge-pipe which leads outboard from the hopper. The outboardend of the discharge-pipe enters an opening in the side of the vesseland is provided with a flange 6, bearing against the inside of the skinof said vessel. The inboard opening of the dischargepipe 5 is providedwith a flange 7, which is bolted to a corresponding flange 8 on thehopper end. The opening 9 of the hopper,which communicates with thedischarge-pipe 5,is of less area than the said discharge-pipe at 10, sothat any solid material .which will-pass through the opening 9 will alsopass through the pipe in the direction of the arrow. In thehopper-opening 9 are placed a number of solid projections 11, thefunction of which is to break 11p clinkers or other solid material inthe ashes before the latter pass to the discharge-pipe.

12, Fig. 2, is a pipe leading from any source of water-supply underpressure and communicating with a suitable form of cock at 13.

At 14 the water-conduit is reduced in area,so

that when the water enters the discharge-pipe 5 it is delivered intheform of a jet directly through said discharge-pipe and so outboard. Thisjet is turned on and off and regulated by means of the valve or cock at13. The rod which is connected to said cock and through which said cockis turned to actuate it is shown at 15 and is journal ed in a bracket16. Secured to said rod at 17 is the operating-handle and also aprojection 18 at an angle to said handle. The mouth of the hopper isclosed by a swinging door 19, hinged upon the rod 20 at the upper sideof the hoppermouth.

Pivoted upon the hopper-flange 4 are swinging bolts, one of which isshown at 21, Fig. 2, which bolts when the door is closed pass throughopenings in said door and receive nuts 22, provided with handles, bymeans of which nuts the door is fastened in closed position. The doormay be provided on its inner side with packing, (represented at'23, Fig.1,) in order that when shut it may make a close joint with thehopper-mouth. In the door is a small opening 24, wherein air isentrained when the device is in operation, which air then produces awhistling sound, indicating that the apparatus is at work, and alsoprevents the formation of apartialvacuum in the hopper.

Pivoted in the discharge-pipe 5 upon a vertical shaft 25 is a valve 26,which may be swung into position longitudinally the pipe to open thedelivery and transversely the pipe to close it. On the upper end of theshaft 25 is secured an arm 27, to which is pivoted a link 28. Theopposite end of said link is pivoted to an arm 29, which is fast uponthe rod 15.

In order to operate the device, the rod 15 is turned, by means of thehandle 17, so as to open the cock at 13 and allow the water-jet to passoutboard through the discharge-pipe 5. The handle 17 will then projectoutward, as shown in Fig. 1, and by reason of the linkage 27 28 29communicating with the valve 26 will place that valve in its openposition, as shown. The-air now being drawn in through the small opening24 in the door will make its Whistling sound, indicating that the jet isin operation. The door is then swung upward, as shown by the dottedlines in Figs. 1 and 2, and is secured in that position by means of thepivoted bolt and nut 30. lVhen the door is in this upward position, itwill be observed that the projection 18 on the rod 15 comes behind it,so that the rod 15 can now not be turned by its handle 17 to shut ofithe water-jet until the door is closed. The ashes to be ejected are nowthrown into the hopper 3 through the door opening. They pass through thehopper-opening 9, the larger masses being broken by the projection 11,as already explained, and thence into the discharge-pipe 5, where thewaterjet from 14 meets them and forces them out through the outboarddelivery-openin g.

It will be seen that the arrangement for preventing the rod 15 beingturned to close the water-jet while the hopper-door is open obviates anydanger of ashes being put into the hopper when there is no jet workingto force them overboard, and thus any possible clogging of the apparatusis avoided.

The discharge-pipe 5 is, as best shown in Fig. 3, arranged at an angleto the fore-andaft line of the vessel, so that the material isdischarged in a direction toward the stern. The object of this is toreduce the resistance which might be offered when the vessel is inmotion and going ahead, especially when the discharge-pipe is locatedbelow the waterline, to the outward movement of the ejected material. InFig. 1 I have shown the waterline at A as above the discharge-openingand at B as below it. It will be understood from this that the apparatusmay be disposed so as to deliver either above or below the waterlevel.

It will be obvious that when the rod 15 is turned so that the projection18 thereon extends outwardly from the bulkhead 2 the door 19 cannot beswung upward to be engaged by the pin and nut 30, Fig. 1; or, in otherWords, the projection 18 must be put into the position shown in Figs. 1and 2 before the door can be secured in its open position; but when theprojection extends outward, as stated, the water-valve at 13 and thevalve 26 in the discharge-pipe are closed. Hence the rod 15 must beturned to open said valves and bring the projection 18 into the positionshown in Figs. 1 and 2 before the door can be secured, as stated.
